To all whom it may; concern;-

Be it known that =1, Marianas Buock, a citizen of the United States, rcsidmg at Boston, in the CG-lint}; of Suffolk and State of Massachusetts, hi ire-invented certain Impreveinci'its in End Last-i-ng and Wiring Mechanisms, of whit' i'i the following desoripuse in the. manufacture of boots and shoes and 'partiouiarly to apparatus for use in minneoti-on with the lasting of the toe porions of shoes. In this operation as carried on with the type of mechanism in which this invention is herein shown-for the purpose of explanation, end embracing wipers are employed in working the upper -ovor the toe port-ion of the shoe into position-tobe fastened to or upon the inner-sole. the manufacture of welt and turn shoes in which the irrnersole "or the sole has a lip or s'houider near its marginal edge it is the custom to secure the upper in lasted position by binding the upstanding edge of the upper against the abutment formed by the said lip or shoulderby a wire or other conti-nuous material. in order to place the wire in binding relation to the overworked upper it has been necessary to displace the wipers or so manipulate them that in some degreethcy fail continuously to hold the upper. 'zIwo practices are common among lasting machine operators. With one type of machine in which there is opportunity to do so the binder strand is threaded across the machine in front of the shoe and under the wipers and then the wipers are raised or their holding pressure upon the shoe is relaxed while the wire isd-ra-wn in under them, between their lower faces vand the upper that is'overlaid on the fcather or margin of the inncrsole, and tightened into binding relation to the upstanding edge portion of the upper. With another type of lasting machine in which the presence of a toe band renders the above descrihd procedure impractical the wipers are partially backed off the shoe to present a narrow channel between their front edges and the upstanding upper. The operator then iays the binding materialin this narspeeiflcation of Lctters'l'atent.

; row channel and tightens it against the upper. In the raising of the wipers and also in backing them off their holding relation to the upper is disturbed and results in more or less disturbance of the position of the upper which they have just worked into the position WhQIQ it ought to be fastened. If the upper hasbeen overworked under tension it siackens back when the wipers partially release it. Not only is neither of these practices compatible with securing the upper while it is in the most favorable position but neither practice provides for the accurate positioning of the wire which is desirable in order to insure that. it'shall bind the upper most effect-ii'ely.

It is an object of this invention to overcome these objectionable features and to secure more accurate positioning of the binder and more satisfactory binding of the upper in the position to which it has'been overworked than has heretofore-been obtained.

A very important feature of this invention consists in lasting means adapted for working an upper into lasted position and holding it under tension and havin pro vision for guiding a binder into binding position against :that portion of the upper held by the lasting means.

A further feature of this invention consists in toe binding means constructed and arranged for positioning a binder. in predetermined binding position against the up standing edge portion of the upper acted upon by the-edge face of the wiper.

A preferred embodiment of the invention comprises a binder positioning i-nember having a wire holding slot or groove in its face extending substantially parallel with the plane of the shoe bottom for placing the binder in a predetermined position against the upper material that is 'to be bound in place.

As herein shown, and in accordance with the preferred embodiment of the first men ti'oned feature of this invention, the end embracing wipers are provided in their act ing face with a slot in which awire may he held in position to be tightened into binding relation to the upper while the wipers remain stationary in the final position'to which they have been moved in overworking the upper. This has thendvantage that the flipper fastened ini'theut ihavsing any The preferred formation of the wire fguid ing means may for convenience be designated as split wipers. A feature of the invention in this is found In means for placing the wire against the upstanding portion,

of upper in a selected position above the foot of such portion of the upper. Shoes which are bound in lastedposition at the toe by wire or other continuous material as a temporary fastening are later sewed by a seam which extends transversely through the upstanding portion of upper and the lip. The binding wire as heretofore applied has frequently been so located that it was liable to be struck by'the needle of the sewing machine and also was liable to be sewed into the seam, thus causing annoyance and sometimes delay to the sewing machine operator. By the use of the present invention in which the wire is placed with certai'nty in a predetermined position, verti cally considered, the slot. in the wiper or other wire holder may be located so as to place the binder just-above the location for the line of stitches so that liability of striking itor sewing it into the seam is avoided.

These and other features of this invention will appear in connection with the' follow-.

of the upper material which is to be bound against the lip of the innersole; Fig. 4 is a modification.

The too lasting mechanism of the drawings may be like that of a well known com; "mercial lasting'machine of the bed type .and needs no further description than to state that the. wipers 2, which are removably mounted on wiper carriers 4 having cam slots 5 by which the direction of their advancing and closing movement is controlled, are actuated by connections with the hand lever 63. In the lasting operation, as is well understood, the wipers are employed to work the upper over the edge of the last feather or reduced marginal portion the iimersole into position"against the lip tension control at the other side.

boun'd. Thewipers 2 are herein provided a with a sl ot 15 extending substantially parallel with theirupper and lower faces from their acting edgesbackwardly toward their operating mechanism and forming a .binder holding and positioning recess. The slot is preferably so extended as to permit the wire to be drawn ina. substantially ri ht line across the machine, as indicated in ig. 1, in.placing it in position for use. This formation presents horizontally split wipers the lower half of-which is of course sufficiently thick and stiff to prevent objectionable springing while overwiping the upper and forming it upon the marginal e'dge'ofthe shoe.

at 14 to facilitate the insertion of the wire which may easily be putinto place by merely stretching it across between the wiper ends and drawing it backwardly into the position shown in Fig. "1. A friction holder '16 may be provided to retain the end of the binder on one side of the machine while the strand runs to a usual reel and As herein shown, the wiper guiding portions 18 of the machine head are extended forwardly to give desirable'support and rigidity to the wipers and are cut away or slotted as at 19in continuation of the wiper slot. The wiper holders t support the wiper plates 2' in such relation, see Fig.3, that theslot 15 is below the holders and the end portions of the wire extend under the holders 4 and into the slots 19 in the cap 18. This arrangement makes it unnecessary to slot the holders It in order to""al1ow the wire to extend across the machine in front of the shoe as shown in Fig. 1. The wipers 2 might be each made in two plates, as indicated in Fig. 3', with the wire holding recess between them or any other convenient manufacturin expedient may be adopted. .The portion 0% the wiper below the slot 15 will preferably be madeof suitable thickness to place the.

wire insueh a relation to thefoot of the upstanding-portion of the upper that it will be above the stitchingline which is at or near the angle between "the horizontal and vertical faces of the upper in a turn shoe and usually somewhat above the angle in a welt shoe.

In using the invention the operator prepares themachine by positioning the binder as shown in Fig. 1, that is, by placing a strand otbinder material or an unformed binder as distinguished from a bent or bowed binder, in the split w-iners. -He then 'la'sts the toe of the shoe in the usual 'way' The mouths of "the slotin the two wipers'are preferably flared as ;:andcauses the wiperstof'remain'intheir and inner-sole and m-wa-rdlya'cros'si the" as in Big. 3 without any possibility of distiirbing' the u er. tying the binder as dlesctibed a ta pidete mined elevation whilgh may be the same all-around the toe inder can safely lie placed high enough, t-d avoid all liability of its being stitchedintd the inseam. This inveiitiori is hot to be c'oiifused with the prior suggestions of a shelf oi: tithei' formation on the wiper plates into whibh a thread or wire was to bebbwed br bent iii order that itmight be carried around the shoe end by the advancing and closing wipers. The present inventio'ii requires nb time c'onsuming manipulatioii-o-f the binder in order to intro duce it in position to be used and no special devices for retaining it.

In Fig. 4 is shown a wiper provided with a spring clamp 20 to hold the end of the binder within the slot. In this construction the wiper slot is not necessarily deep as in the wipers shown in the other figures .but may be merely a deep groove into which a body portion of the binding materia'i may be retained behind the spring clamps 20.
